The Processes Made In ROWPU 3000 Water Treatment Unit

By Michelle Cook


A reverse osmosis or RO is a technology that is used for purifying. It uses a membrane which is semi permeable for removing the molecules, ions, and some other larger particles from the drinking water. It also uses an applied pressure for overcoming any osmotic pressure which is a colligative property driven by some chemical differences of solvent.

This technology is also being used mostly in the production of potable water and also in some industrial processes. The result for this is that the solute is retained to the side of membrane being pressurized and solvent passes to another side. Membranes will only allow the passage of smaller components like solvent molecules. ROWPU 3000 water treatment unit or reverse osmosis purification unit is mainly used for military purposes.

There are many drinking purification systems today which are widely used and reverse osmosis is considered one of the steps used. Some steps used are sediment filters, activated carbon filters, second sediment filters, second carbon filters, and the ultraviolet lamp. Separating the pure waters from the brackish waters is one important application of osmosis.

The membranes which are utilized for osmosis contain dense layers inside the polymer matrix where in the separation will occur. Mostly, membranes are only designed in order to allow waters pass through dense layers while not allowing solutes to pass such as ions. The osmosis process is popular because of desalination or separating the salt from seawaters to produce fresh waters.

The 3000 gallon ROWPU is mainly utilized by the militaries or armies for water purification. The process helps in the treatment of waters from being brackish or being fresh, and being contaminated. The system is stationed within an ISO container of 8 x 8 x 20 feet. The container is mounted on the military trailer of 30 feet. Its source of power is a generator having 60 kilowatts and found at the back of the trailer.

This system is designed for purifying 3000 gallons in a 77 degree Fahrenheit for only one hour. One of the factors that will most likely affect the production rate is turbidity. This system has also the capability of effectively removing concentration from the agents, chemicals, and nuclear radioactive origin of products that are hazardous.

So here are the ways on how this treatment unit is being processed. First is the raw system draws it from the source through a course screen. The raw pump will then be filled and it is turned on, pulling air from the suction hose and pulling it up from the pump as well. So for it to be pulled up quickly, a prime which is hand operated must be used.

For initial priming, a can or hand pump will be used. By the use of hand pumps, lifting it through hose sections will only take two to three minutes, and if not, it takes six to eight minutes when lifting. When the pump is primed already, suctions and check valves will prevent it from running back down to its source.

The raw pump pressure delivers it to separators where it is swirled in fast speed. This is done in order to throw away the sand and dirt through the waste hoses. If it passes in separators, it will be delivered to ROWPU vans and the booster pump suctions will feed the pressurized waters to the infiltration components.
